Can emergency contraception prevent implantation of the fertilized egg?

Patient's question:

No

Doctor's answer:

Hello, it is generally not advisable to take emergency contraception more than twice a month or more than three times a year. Excessive use may lead to menstrual irregularities, so it is important to monitor your condition. If you experience menstrual irregularities, you can take Wuji Baifeng pills or traditional Chinese herbal medicine for regulation. Maintaining a positive mood and getting adequate sleep can help restore your cycle.
